Plant Description
The West Damietta site is located on the Mediterranean Sea north coast, 15 km west of the New Damietta port near Damietta City. The existing facility consists of four (4) outdoor combustion turbine generators (CTGs) GE Frame 9E (4 x 125 MW) installed and commissioned in 2011. The new project accommodates one combined cycle module. It has a 4x4x1 configuration consisting of four (4) combustion turbines from the existing units. Each one feeds its exhaust gases to its respective heat recovery steam generator (HRSG), for a total of four (4) HRSGs and one 250 MW nominal steam turbine unit. Steam generated from the four (4) HRSGs feeds one 250 MW, non-reheat, condensing steam turbine generator (STG).
The new facility estimated 250 MW net output is achieved by burning natural gas in the CTGs with no supplementary firing in the HRSGs. The steam exhausted from the steam turbine is discharged into air cooled condenser. Air is used for the power plant cooling demand. Power generated is stepped up through a main transformer and fed to the utility grid via an onsite GIS existing switchyard facility 220 kV over head transmission line (OHTL). The current switchyard has space for one spare bay adequate for the new steam turbine unit.
The project contracting plan utilized a multi-package system. Eight (8) contracting packages and purchase orders procured the equipment and services.
Plant Description
Al Shabab site is located 33 Km West and 10 km South of Ismailia and El-Kassassin Cities respectively, in the Ismailia Governorate. The existing facility consists of eight (8) outdoor combustion turbine generators (CTGs) GE Frame 9E (8 x 125 MW) installed and commissioned in 2011.
The new project accommodates two (2) combined cycle modules. Both modules have a 4x4x1 configuration consisting of four (4) combustion turbines from the existing units. Each one feeds its exhaust gases to its respective heat recovery steam generator (HRSG) for a total of four (4) HRSGs and one 250 MW nominal steam turbine unit. Steam generated from the four (4) HRSGs feeds one 250 MW, non- reheat, condensing steam turbine generator (STG).
The new facility estimated 500 MW net output is achieved when burning natural gas in the CTGs with no supplementary firing in the HRSGs. The steam exhausted from the steam turbine is discharged into an air cooled condenser. Air is used for the power plant cooling demand. Power generated is stepped up through main transformers and fed to the utility grid via an onsite GIS existing switchyard facility 220 kV over head transmission line (OHTL). The current switchyard has space for two spare bays adequate for the new steam turbine units.
